NATIONAL FOREWORD
This Indian Standard ( Part 2 ) ( Fourth Revision ) which is identical with ISO 4017 : 1999
‘Hexagon head screws — Product grades A and B’ issued by the International Organization for
Standardization ( ISO ) was adopted by the Bureau of Indian Standards on the recommendation of the
Bolts, Nuts and Fasteners Accessories Sectional Committee and approval of the Basic and Production
Engineering Division Council.
IS 1364 was originally published in 1960 and first revised in 1967. Subsequent to the publication
of 1967 edition, many changes had been agreed upon at international level which have been reflected
in IS 1367 series of standards covering ‘Technical supply conditions for threaded steel fasteners’.
Accordingly, second revision was published in 1983 splitting the standard into 5 parts covering hexagon
head bolts, hexagon head screws, hexagon nuts, hexagon thin nuts ( chamfered ) and hexagon thin
nuts ( unchamfered ),
The third revision of this standard was published in 1992 by adoption of ISO 4017:1988. This fourth
revision has been prepared by adoption of latest version of ISO 4017 published in 1999. The remaining
parts of the standard, that is, Part 1, Part 3, Part 4 and Part 5 are also being revised by adopting the
corresponding latest editions of ISO Standards published in 1999.
The Committee also decided to publish Indian Standard on ‘Hexagon nuts, style 2 — Product grades A
and B’ as Part 6 of IS 1364. The Part 6 will supersede lS/lSO 4033:1979 on its publication.
In 1967 version of this standard, the widths across flat dimensions for Ml Oand Ml 2 size fasteners
were specified as 17 mm and 19 mm respectively. However, in the 1983 version, these widths across
flat dimensions were brought in line with ISO 4017 : 1979 and specified as 16 mm and 18 mm
respectively for Ml Oand Ml 2 size fasteners. Recognizing the difficulty of immediate changeover to
new width across flat dimensions, the Committee decided to permit width across flat dimensions as
per 1967 version, that is, 17 mm and 19 mm for M1O and M12 size fasteners till 31 December 1994.

Now it is expected that the e ntire fastener industry would have switched over to new width across flat

dimensions and from 1 January 1995, no old width across flat dimensions shall be permitted.
The text of ISO Standard has been approved as suitable for publication as Indian Standard without
deviations. Certain terminology and conventions are, however, not identical to those used in Indian
Standards. Attention is drawn especially to the following:
a) Wherever the words ‘International Standard’ appear referring to this standard, they should be
read as ‘Indian Standard’.
b) Comma ( ,) has been used as a decimal marker while in Indian Standards, the current practice
is to use a point ( .) as the decimal marker.
In this adopted standard, reference appears to certain International Standards for which Indian
Standards also exist. The corresponding Indian Standards which are to be substituted in their place
are listed below along with their degree of equivalence for the editions indicated:
